The global economic crisis has also had a positive side – the consumption of crude oil fell slightly in 2008 and 2009. Yet before long, it is likely to rise again to about 85 million barrels per day. The International Energy Agency's World Energy Outlook 2009 report states that demand will rise by a further percent each year to 105 million barrels per day by 2030. For how long can we meet this growing demand

The first, purely electrically-driven compact and sports cars are already on the market, but they are much more expensive than their classic diesel or petrol engine counterparts and have a range of no more than 100 kilometres. Only light, high-performance and cheap lithium-ion batteries will help electric cars achieve a breakthrough. Will such electricity storage devices reach production standard in the near future?

Because of NASA's achievements, the United States continues to be regarded as the most important and strongest nation with regard to space. Until now, the relationship with other countries, including Germany, has been characterised by the fundamental view that all American missions should be realised using American expertise on the critical path. The future role of partners was a central subject during the visit by Charles Bolden.

In cars with internal combustion engines, a large part of the energy stored in diesel or petrol is simply dissipated as lost heat. It is precisely these hot exhaust gases that an increasing number of scientists worldwide want to use for more efficient electricity generation. They are developing and testing thermoelectric generators that can generate electricity from temperature differences of several hundred degrees. But does electricity from hot car exhaust gases really save fuel?

A very special experience: I had the opportunity to observe at first hand the work of DLR's staff on Solar Impulse, Bertrand Piccard and André Borschberg's project to circumnavigate the world in a solar-powered plane.

Our Sun is a gigantic fusion reactor with an expected lifetime of about ten billion years. Although this period of time is unimaginably long from a human perspective, half of it has already elapsed. That means that our star, a very ordinary one in astronomical terms, will still be radiating the same amount of energy as it now does long after our resources of uranium, coal, gas or crude oil have been used up. How much energy from the Sun reaches us here on Earth?

Can we refuel in the future simply using the Sun? How long will the Earth’s oil reserves last? Which energy source will our grandchildren use? Many people are asking scientific researchers about the future of our energy supply. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) has chosen the slogan ‘The Future of Energy’ for Science Year 2010. In the DLR Energy Blog, science journalist Jan Oliver Löfken will answer a question about energy each week during the year.

My blog as Chairman of DLR has been set up to communicate internally and externally, focusing not only on general topics but also giving more personal insights. With this in mind, here, at the turn of the year, is the first article.

Today, we have taken our new DLR Blogs platform live; we wish to offer you a warm welcome. We are starting with three blogs. Firstly, there is a blog by Jan Wörner, chairman of the DLR Executive board, who offers insights into his work. Secondly, we have started our NewsBlog, in which we intend to publish the short stories, pictures, videos or other items of interest that do not find a place on the homepage of our web portal – www.dlr.de/en. Last but not least, there's the EnergyBlog. The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung; BMBF) has nominated 'The Future of Energy' as the topic for the german Science Year 2010. This is more than sufficient reason for us to address the subject with a dedicated blog, in which we will also answer an 'Energy Question of the Week'.
